SOME MODELS FOR SELECTION
PVC is one of the widely used plastics, and PVC is a non-crystalline material. Industrially produced PVC has a degree of polymerization between 500 and 2000.
PVC is a non-toxic and odorless white powder. PVC plastic has a density of 1.40g/cm3, PVC with plasticizer and filler added
The density of the plastic is usually from 1.15 to 2.00 g/cm3, the glass transition temperature is 87 ° C, and the melting point is from 160 to 212 °C.
PVC begins to soften at 65-85 °C, and becomes viscous at 170 °C. At 140 °C, a small amount of decomposition begins. As the temperature increases, the solution speed increases, and a large amount of HCL gas is released above 190 °C. PVC has a chlorine content of up to 56%, so it has flame retardancy and self-extinguishing properties; and it has good dielectric properties, and smooth plastic pipe is an excellent electrical insulating material.
PVC has less water absorption, usually below 0.1%
